A suspect charged in the murder of D12 rapper DeShaun "Proof" Holton was convicted on weapons charges related to the incident.

After a three-day trial, Mario Etheridge, 28, was found guilty of carrying a concealed weapon and shooting the firearm indoors after the April 11th shootout in a Detroit nightclub, that left Proof and one other individual dead.

He faces up to five years in prison if convicted.

Etheridge, a bouncer at the club, allegedly fired warning shots inside the building in an attempt to break up a fight between the rapper, 32, and Keith Bender Jr., 35.

Proof, who police said shot and killed Bender, was then shot by Etheridge moments after the altercation escalated.

"There was too much testosterone in the club, and he added another cupful," assistant county prosectutor Elizabeth Walker told Detroit News reporters after the verdict. "You're not going to make a situation better by bringing a gun into it.

Etheridge remains free on bond until sentencing.

He was secretly escorted from the courthouse due to threats of revenge directed towards him by Proof supporters.
